On the newest update for Minecraft Bedrock Edition, released on Feb 24, 2023 as PlayStation’s 2.58 version, I encountered a glitch that entirely wipes an inventory on a survival world when loading in. I resolved it by immediately turning off my system. When I got back into the world, since it had not saved, I had kept my stuff. However, this may only be a temporary solution. There could certainly be a chance that it wipes it for good.
